In the present study we employed an animal model of MS, the Experimental Autoimmune Encephalomyelitis (EAE) to explore the in vivo uptake of fluorine (19F) nanoparticles by inflammatory cells during encephalomyleitis. Using a 32-leg 1H/19F birdcage coil dedicated for mouse head imaging, we detected and quantified 19F nanoparticles (containing perfluoro-15-crown-5-ether) taken up and transported by macrophages within the cerebellum following intravenous application. The application of 19F nanoparticles for imaging immune cells in conditions such as encephalomyelitis is an emerging field that will be ideal to study the kinetics of immune cell localization during the development of inflammation.
